That's poking fun at a common contract clause called a severability clause[1]. The idea is that if one provision is held unenforceable (say, an unconscionable arbitration clause or limitation on damages), the rest of the agreement remains in force. These came about because some courts have found that the unenforceability of some clause in an agreement changed the bargain such that it wouldn't be fair to allow the rest of the agreement to remain in force.
